90+1 Chelsea have slowed the pace down now.
90 There will be three very long minutes of optional time for an embattled Blackburn outfit.

88 However, Rovers manage to intercept and bang the ball up-field
87 Drogba muscles his way past two defenders and attempts to pass the ball to Ballack out wide.

85 The final whistle just can't come soon enough for the visitors.

83 Diouf tries his luck from range. But he doesn't catch the volley properly and the ball flies well wide of Cech's goal.
82 That said Blackburn have enjoyed a decent spell of possession.
81 One has to feel for Robinson. He hasn't put a foot wrong yet has conceded five goals. And it was a similar story when Blackburn lost 6-2 to Arsenal.
80 Drogba lays the ball off to Sturridge but he makes poor contact and Robinson collects.
79 Hoillett's cross is headed away by Terry and Chelsea counter immediately.
78 Joe Cole gets a standing ovation from the Bridge faithful after an excellent comeback showing. Daniel Sturridge will have just over ten minutes to prove his worth to Carlo Ancelotti.

76 Drogba drifts out to the wing on the left and knocks in a cross that is well blocked by a Blackburn defender.
75 Robinson is forced to make a sharp save from Anelka's shot from the edge of the box. But it wouldn't have counted as Lampard of all people was offside.

73 Hoillett cuts inside and takes a pop at goal. But the weak shot trickles well wide of Cech's upright.

63 GOAL DROGBA! Ballack swings in a corner and Drogba rises highest and with his head flicks the ball past Robinson to continue the rout.
62 Drogba appeals for another penalty as Robinson appears to make contact with the Ivorian and not the ball. Wiley seems to have some sympathy for Rovers and this time says 'no penalty'.

53 Kalinic comes on for Blackburn. Roberts is the man to make way.

51 Big Sam is pondering a change as Nikola Kalinic readies for action.
50 Chelsea are in a rampant mood now and Essien is revelling in midfield.
49 Blackburn really have their backs against the wall now.
48 GOAL LAMPARD! A lovely through ball from Essien starts the move as Drogba gets beyond his marker in the area. The striker squares the ball and Lars Jacobsen does well to deflect the ball away from goal. But Lampard is perfectly positioned to latch onto the rebound and he places the ball past Robinson to double Chelsea's lead.
47 The Londoners go on the attack straight away and Ivanovic swings in a cross that is cleared by Givet.
46 The second half has started with Rovers playing from right to left.
It's not looking good for Blackburn so far and the bookmakers at Sky Bet agree. They are 66/1 to come back and win.
That's the interval folks. Chelsea might feel aggrieved that they only lead by one goal while Big Sam will be patting his goalkeeper on the back for keeping his men in the match.
45+2 After a goal-mouth scramble the ball drops to Terry and Robinson makes a fine save from his volley. Another corner follows and the Rovers 'keeper eventually gathers the ball after a bit of a fumble.

43 It is Drogba who steps up and the effort crashes into the wall. The rebound falls to Lampard and his shot is wide of Robinson's goal.

39 Lampard also tries his luck from range but doesn't strike the ball cleanly.

37 A mistake from Cech almost lets Diouf in as the goalkeeper misses a punch from Pedersen's long throw.
36 Pedersen's cross looks for Emerton in the area in a rare Blackburn attack. Terry deals with the danger comfortably.

33 Robinson is called into action again as he blocks Anelka's shot following great work from Lampard and Cole on the edge of the 'D',
32 Again Rovers find themselves under pressure. Nelsen heads clear a cross but only as far as Ballack who whips the ball back in. Lampard surprisingly wins the aerial battle and heads straight at Robinson.
31 So just over half an hour gone at the Bridge and Chelsea are full value for their lead.
30 Space opens up in front of Essien and the Ghana international fancies a crack from distance. The shot is however always rising and Rovers have a goal-kick.

28 There's another stoppage as Ryan Nelsen takes a breather after a challenge with Drogba.
27 Roberts finally latches onto a long ball. Terry marks him tightly so the striker lays the ball off for Pedersen but his daisy-cutter spins wide of the upright.

25 Rovers are still trying to knock the ball long but Roberts is totally isolated up front.
24 Blackburn's backline is under siege and Ballack's cracking shot is blocked by Givet, who atones for his earlier error somewhat.

21 Blackburn try to regroup after going a goal down under unfortunate circumstances.
20 OWN-GOAL GIVET! A quick counter-attack from Chelsea tears open the Blackburn defence. Ballack releases Anelka down the left wing and the striker's low cross is turned in by Givet under serious pressure from a certain Didier Drogba.
19 Chelsea get a shot at goal after Lampard and Cole combine well. But the latter's toe-poke hasn't the power to trouble Robinson.

11 El Hadji Diouf looks like Blackburn's primary attacking weapon but he's been closely watched by the Blues rearguard.

2 Drogba's clever ball over the top is chased by Anelka, but the Frenchman doesn't have the pace to get on the end of it.
